The compressor is often called the heart of an air conditioning system. It circulates refrigerant and drives the entire cooling process. It is also the most expensive component to replace, so understanding what causes failure can help you protect it.
Low or Overcharged Refrigerant
Running a system with low refrigerant from a leak forces the compressor to work harder and overheat. Overcharging is equally harmful, causing liquid refrigerant to enter and damage the compressor. Correct refrigerant levels are essential.
Electrical Problems
Failing capacitors, damaged wiring and power surges all stress the compressor's motor. Over time, electrical faults can burn out the windings, leading to complete failure.
Dirty Coils and Poor Airflow
When the condenser coil is caked with dirt, the system cannot release heat efficiently, causing the compressor to overheat. Restricted airflow from dirty filters has a similar effect, making the compressor run hot and hard.
Inadequate Lubrication
Like any motor, the compressor needs proper lubrication. Low oil levels, often tied to refrigerant problems, increase friction and wear until the unit seizes.
Age and Neglect
Years of operation without maintenance take a toll. Small issues that go unaddressed compound and shorten the compressor's life.
How to Protect It
Annual maintenance is the best defense. Keeping refrigerant charged correctly, coils clean, filters fresh and electrical components in good condition dramatically reduces the risk of compressor failure. Because replacing a compressor often costs a large share of a new system, prevention is well worth it.
